4 Claims. (Cl. 311-4) This invention relates to tables formed of a number of sections, and adapted for use as cutting tables.

An object of the invention is to provide an improved construction for a table of the class described having a number of sections which are adapted to flt together to form the complete table.

Another object'of the invention is to providea sectional table of the class described the interfitting parts of which are characterized by considerable novelty, so that the desired length of table may be assembled quickly and easily and without the use of special tools, and as readily disassembled.

A further object of the invention is to provide a sectional table comprising a number of sectional elements, including end elements and intermediate elements, and having novel joint means for providing at the points of intersection of .the adjacent elements of the table, smooth interconnection so that the entire length of the table top remains plane.

Still another object of the invention is to provide a highly improved cloth laying up table for use in cutting rooms and the like, which may be made as long or as short as desired, by merely assembling sufllcient sectional elements of the table together, and having a smooth table top formed of sheet material which is securely fastened down particularly well at the joints between adjacent table sections.

Still another object of the invention is to provide an improved construction for a sectional cloth laying up table which has an all aluminum construction and is therefore light in weight yet strong in its ability to support the weights to be disposed thereupon, and which has a sectional plane top made of fibrous sheet material such as Masonite pressed wood and the like.

A further object of the invention is to provide an improved sectional cloth laying up table which is simple in design, inexpensive to construct, and easily and quickly assembled and disassembled without special tools other than for example a screw driver and pliers.

Other objects and advantages of the invention will become apparent from the. following description of a preferred embodiment thereof as illustrated in the accompanying drawings, and in which:

Fig. 10 is a fragmentary sectional elevation similar to that of Fig. 3, but showing a modified form of table top construction.

The present invention discloses a novel form of cloth layingup table adapted for use as a cutting table or for other desired purposes, which is made up of a number of sections, each section being small enough to be handled conveniently by one or two men, and which are designed to be assembled together with the greatest of ease and convenience, to form a sturdy table of the desired length.

In order to understand clearly the nature of the invention and the best means for carrying it out, reference may now be had to the drawings, in which like numerals denote similar parts throughout the several views.

As shown best in Figs. 1 through 5, the table is formed of a number of intermediate table sec-' tions such as those generally indicated at 20 and 22, and two end table sections one of which is generally indicated at 24. It is apparent that a table of any desired length may be formed by assembling a number of intermediate table sec-.

tions like those shown at 20 and 22 to each other and between two table end sections, the left end one of which is shown at 24.

The table is supported upon any suitable type vertical legs such as those shown at 26 and 30, these being disposed at intervals along opposite edges of the table to maintain the elevation of the table top 32 above the floor. The table top 3; 0t each section is preferably formed of suitgral legs such as at 30 depend fromopposite ends along their margins extending laterally across the width of the table, to form marginal groovelike rei esses or seats 34 shown in Figs. 1 through Y 5, and numbered 34A in Figure 6. Seated in these marginal recesses 34 are the opposite top flanges 36 and 38 of the T-shaped channel member 40 made of aluminum or other suitable material, which extends right across the joint between adjacent sections of. the table top 32, two of these T-shaped channel members 40 being shown in Fig. 1. V

The T-shaped channel member 40 has a vertical'web 42 which extends downward between the'remaining edges ofthe sections of the table top 32, as seen best in Figs. 2 and 4, so as to have the top flanges 36 and 38 overlie these remaining edges. As seen best in Figures 4 and 5, the table top 32 lies upon the top walls 46 of a number of longitudinal support channels 44 which are disposed thereunder inside by side relation, the

side walls 48 of adjacent support channels being in mutual contact, and the bottoms of the side walls 48 being turned inward toward each other to form bottom flanges 50.

tached to the underlying cross channel I2, as

shown inFig. 2, and-which will be hereinafter more fully described. Fig. shows a modified form of construction of the support channel members 443, it being seen that each channel has a top 463, one side wall 483 with inturned flange 50B, and an opposite side wall 480 the lower edge of which extends slightly lower down than sidewall 483, so as to allow itsoutwardly extended flange 50C to underlie the inturned flange 50B of the adjacent channel, so as to be secured thereto and to the underlying channel by means of a single screw or bolt 60 mtead of two screws 82 as in the Figs. 1 through 5 form.

It will thus be seen that the vertical web 42 of the T-shaped member 40 also spaces adjacent edges 62 of the adjacent table sections, so that the undercut edges of the table top sheets 32 are pushed in between the under surfaces of the.

support members 44 on the left as seen inFigs. 2

and '4 to bring their faces flush with the right edges 62 of the channel support members shown having a top wall I4, one depending outer flange I6, and another inner depending flange I8 which is cam grooved at 80, in a substantially V- shaped cross-sectional contour. A screw 82 holds the cross channel I2 in position as shown, and inteof the cross channel to support the table.

The right hand table section of Fig. 2 also has an underlying cross channel 90 with its top on the left of Fig. 2, and are secured to the web 420i the T-shaped joint member 40 by means of a screw 'I0'exten'dingthrough the web 42 and the face of the face plates 66, as seen'best in Fig. 2. To the support channels on the, right side of Figs. 2 and 4 are secured similar face plates 66A by spot welding as at 68A, these face plates not being brought all the way over to the left edge of the right support channels of the View since it is necessary that they allowroom for clearance of the screw head of screw .10.

The left hand table-section 24 of Figs. 2 and 4 is provided with an underlying cross channel I2 32 secured to the bottom flange of the face plate A by screw 94 as shown, and having an outer flange 96 and an inner flange 98 which is provided with an outward ridge I00 corresponding to thegroove 80. It will be seen from Fig. 2 that the'right hand edge of the cross channel 12 extends further to the right topartly underlie the bottom flange of face plate 66A, and that the left hand edge of the cross channel 90 is oflset to the right to allow for this overlap. In addition, the centerline of the projecting ridge I00 is slightly higher than that of the left hand groove 80 so that when drawn together by the screw I02 during assembly, a cam action arises drawing the table section 20 downwardly or upwardly with respect to the table section 24 which makes for a more secure, rigid and level assembly.

In accordance with our invention, all the edges of the intermediate table sections except the edges adjacent the joint member 40 are covered with edge channel moldings I04 formed of aluminum or other material, with their upper flanges I06 extending into marginal recesses formed by undercutting the pressed wood tablev top 32.

Their bottom flanges I08 are secured to the lower flanges 50 of the channel support members 44 by means of bolts IIO. (See Fig. 2.)

Similar edge molding H2 is securedto the end edges of the end sections 24.

Figs. 8 and 9 show a modified form of' edge molding I0 4A for the intermediate table sections.

and end sections, having a ledge I I4 forming a seat for the rail supporting chairs or brackets II 6 disposed therealong; The chairs II6 have downwardly open slots II8 formed therein to receive therethrough bolts I 20, the said bolts I20 extending also through the longitudinal track I22 which is adapted to support the traction wheels of the cloth laying machine described further in thereto by the nut m. A groove I26 is formed in the outer surface of the edge molding I 04A to serve as a guide for drilling to receive the bolt I20.

In Figs. 6 and 7 we have shown a modified form of the invention for the table. section joints in which the T-s'haped 'channel'member 40A has additional lower oppositely extending side flanges I28 and I30, integral with its web 42A, each side flange having a longitudinally extending cam surface I 32. In this form of our invention the 38A and I30 (as in Fig. 6), the cam action of.

the portions I32 holds them securely in position, and the depending lower ridge I40 serves as an through the parts additional spacer to prevent crushing or buckling of the Masonite table top.

Although I have described my invention in specific terms, it is to be understood that various changes may be made in size, shape, materials and arrangement without departing from the spirit and scope of the claims.
